Abstract

This research aimed to examine Sains, Technology, Engineering, Mathematics (STEM) learning approach effectivity in increasing scientific literacy of senior high school students. The research involved 67Senior High School 5 students Bandar Lampung in Lampung Province, Indonesia. The research design used was the-Equivalent Control Group Pretest and Posttest Design. The experimental class used STEM Learning Approach, and the control class used a scientific approach. The data was collected using pretest and posttest score of scientific literacy inventory. The Effectiveness analysis was done using the Normalized Gain (N–Gain) and Effect Size. Based on the research, the average score of the scientific literacy skill with N-gain of experimental classes was 0.55 and control class was 0.49, both classes were in medium category achievement. The result of effect size test showed that STEM learning approach has an effect size in the medium category of 0.24. Furthermore, based on an analysis of T-test results, there was a difference between the N-gain average score of the students' scientific literacy skill between experimental class and control class. The students who learned with STEM learning approach has a significantly higher degree of scientific literacy skill than those who learned with the scientific approach. So the conclusion in this research is that the students taught using the STEM approach are in the "conceptual" category which is better in explaining the concept, able to describe the relationship between these concepts, and able to analyze alternative solutions and procedural skills and understanding of the process of discovering science and technology.

Abstract

To ensure the success of science learning oriented to higher order thinking skills, especially scientific communication skills (SCS), valid and effective instruments are needed. The existing instruments, although helpful, are still too general and have not touched the socio-cultural context. Therefore, we developed an instrument to measure SCS according to the characteristics of students in Indonesia. This study tested the validity, reliability and assumptions of the hypothetical model of the scientific communication skills inventory (SCSI) instrument developed. This study involved 1,287 students in Indonesia. The test was carried out through confirmatory factor analysis with structural equation modelling (SEM) using AMOS version 21. The results of the analysis show that the reliability of the instrument based on Cronbach’s alpha coefficient is 0.720. The convergent validity test detected one item of the oral presentation indicator as invalid and the discriminant validity test confirmed that all instrument items were declared valid. The goodness of fit test shows all scores according to the recommended standard criteria so that SCSI can be used to identify the SCS ability profile of students in Indonesia. For further research, we recommend the development of a learning model that prioritizes the context of social issues to grow students’ SCS.
